CARL ADAM NEUBEOKER, OF OFFENBACH-ON-THE-MAIN, GERMANY.

MACHINE FOR DRIVING HOOPS UPON BARRELS OR CASKS.

SPECIFICATION forming part of Letters Patent No. 625,409, dated May 23, 1899.

Application filed May 5, 1897. Serial No. 635,182. (No model.)

To all whom it may concern:

Be it known that LOARL ADAM NEUBECKER, manufacturer, of a l Ludwigstrasse, Offenbach-on-the-Main, in the Empire of Germany, have invented Improvements in Machines for Driving Hoops Upon Barrels or (Jasks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a machine for driving hoops upon barrels to tighten said hoops simultaneously and uniformly upon both ends of the barrel, even if the hoops are not placed at an equal distance from the middle of said barrel. It is even possible with this machine to secure hoops upon barrels that have three hoops at one end and only two at the other, as the centering-plates, by means of which the barrel is brought in the center of the machine, permit of a correspondingly greater displacement of the barrels from the center.

The accompanying drawings show as an instance one form of construction of the subject-matter of the invention, in which Figure 1 is a vertical section through the subject-matter of the invention; Fig. 2, a lateral view thereof; Fig. 3, a plan view of the mechanism for displacing the claws; Fig. 4, a diagrammatical view of the upper centering-plate F; Fig. 5, a plan view of the lower centering-plate F, Figs. 6 and 7 each show, as an instance, a vertical view of one form of construction of the invention; and Fig. 8 is an elevation of the machine, showing a barrel with two hoops on one end and three on the other.

In a fixed frame A, Figs. 1, 2, 3, 4, and 5, the two double-acting hydraulic cylinders B B are arranged, the pistons D and D of which can move in such a manner in the frame or casing A that the water fed through M and R can flow in at the top or bottom of the piston, according to the turn which is given to the four-way cock H. The guide-rods P P, located in the hydraulic pistons D and D and which are movable therein, carry the plates F and F, which serve for centering the barrel and of which the upper plate F is heavier than the lower plate in order that by its weight it can bring the said barrel in the center of the pressing-plates E and E, respectively, of the claws f. The pressing-plates E and E, the cross-section of which has the form of an angle-iron and which encircle the plates 0 0, Fig. 3, are fixed to the hydraulic cylinders D and D. To these plates are attached the claws f, which project through corresponding openings in the covering-plates S S. These plates S S cover directly the plates 0. In order that both pressing-plates E E, with the claws f, can uniformly move toward each other and away from each other, they are suspended from chains or cables a, which run over rollers 11, fixed to the frame A. Any other equalizing device may also be used. The plates F F are similarly connected by means of chains or cables d, which run over rollers c.

In the constructions illustrated as an instance in Figs. 1 and; 2 the four-way cock H is turned in such a position that the water can run in through the pipe M back of the pistons DD, so that the hoops can be set toward the middle of the barrel. If, however, the four-way cock is turned ninety degrees, the feed-water will pass through the pipe R in front of the pistons D D and will move the pistons, and at the same time the claws, away from the barrels, whereby the water back of D can run out through the pipe M. The pistons D and D can be held in any desired position by the operation of the straight passage, Fig. 3, in the cock H, as the pressure of the water at the top of the piston will be equal to that at the bottom thereof. After the claws ff have been withdrawn from the barrel until they pass beyond the centeringplates F F the centering-plates are automatically carried back with the pressing-plates, because the lug g on the rack-rod a strikes plate F. Plate F will follow also, because it is connected with F. The object of the centering-plates is solely to bring the barrel in the center of the machine before the hoops are driven upon the same that is to say, dur ing the operation of the machine the plate F and the barrel are drawn upward by the heavy upper plate F until the barrel comes in contact with the plate F and a further approachment between the plates F and F is prevented, while the plates E and E, with claws, continue to come nearer each other. If now, for instance, the hoops at the top are farther distant from the middle of the barrel than those at the bottom, the upper claws will first close in upon the hoops and will press down barrel, in which case the barrel and the upper plate F will be pressed upward, while the plate F will move away from the barrel. Thus as soon as the claws close in upon the hoops the function of the centeringplates ceases. In order that the apparatus can be used for barrels of any diameter, the claws f are radially adjustable, which adjustment can be efiected by means of the plates 0 0, bearing in the angles of the plates E E, Fig. 3. By a turn of the plate 0 the sliding blocks G G, which are connected with the claws, can be made to take position in the sloti at various distances from the center, according to the turn which is imparted to the plates 0 and O. In order to make this rotation possible, the plates 0 and O are provided with a toothed segment, which engages with the toothed wheel R. The large toothed wheel m is arranged upon the same shaft Z with the toothed wheel 70. The large toothed wheel engages with the toothed wheel '11. This toothed Wheel n can be turned in any desired position by means of the handle Q, fixed upon the axle 1) thereof. The shaftl is provided with a wedge-shaped groove o of proper length, which permits of a vertical displacement of the toothed wheels 70 and plates E and E, so that the upper and lower pressing-plates E and E and the claws ff can be pressed simultaneously against the barrel and moved away therefrom. As a consequence of the displacement of the claws caused by the turning of the plates 0 O the barrel can also at the same time be centered exactly in the middle of the centering-plate F.

Figs. 6 and 7 show, as an example, another form of construction, wherein the connection between the pressing-plates E and E and the centering-plates F F is established by a lever or a rack. For clearness sake the compulsory connection of the pressing-plates E and E by the levers c and b, as well as the rods (1 and a, Fig. 6, or by the racks d and CL with the toothed wheels 0 and b, Fig. 7, has been shown from one side only. In the form of construction shown as an example in Fig. 7 these toothed wheels 0 and b are rotatably arranged upon the frame A itself. The clawsfcan be pressed inward by means of springs z, fixed to the sliding blocks 0, in order that they can be used with barrels of no matter what shape, whether round or of another shape.

Having described my invention, I claim- In a machine for driving hoops upon barrels, the combination of the centering-plates F, F, connected by motion-equalizing devices and having a tendency to close upon and automatically center the barrel with pressingplates E, E carrying the hoop-drivers f adapted and arranged to carry the centering-plates with them in the separating motion but in the driving motion to move independently of the centering-plates, so that if the hoops on opposite ends are not in uniform position, the barrel maybe so displaced that both hoops shall be driven simultaneously, substantially as described.
